Overview: Intelligent Digital Amplifier PWM Controller and Audio Processor
D2-45057, D2-45157
The D2-45057 and D2-45157 devices are plete System-on-Chip (SoC) Class-D digital audio amplifiers. bining high performance integrated Power Stages along with an optimized Audio Processor feature set and PWM Controller, these devices offer a plete, powerful, and very cost effective audio solution for high volume and cost-critical products. This 4th generation Digital Audio Engine (DAE-4P)™ device bines extensive integrated Digital Signal Processor (DSP) audio processing with amplifier control, for a plete audio solution. Its ease of integration into the existing system processor provides plete support for all system product and amplifier functions. The four configurable Power Stages operate as four separate Half-Bridge outputs, as two Full-Bridge outputs, or in binations of Half-Bridge plus Full-Bridge, providing flexible loudspeaker drive solutions. Separate PWM outputs provide additional binations to drive headphone, or line level stereo and subwoofer outputs.
